UNITED STATES PATENT OFFECE GEORGE .ivronnrsolv, or iOUGnnEEPSIE, NEWYORK I V I I VENDING MACHINE Application filedhiigust 14, 1930, SerialNo. 475,169.

This invention relates to a, Vending ma} as this 1S 2% matter Of detail1101] iIIVOlVGCl 111 chine for dispensing articles, one at a time theinvention and which will have to be and is controlled. bynovel'inechanism which p d o s lt local conditions, and also it isreleased by the insertion of the 'proper coin y be Stated that a numberof themilchines 5 which allows one article to be ejected "for each E ybe mountedt g in a g 155 @0111 in rt d, caslng if desired.

The object ofthe invention is to provide the d i e as here shown; theres P a novel brake or cushion whereby the con- Vldedv m s P a 10 be veyoron whichis mounted the supports for cured Wlthln a 9 m a to thlsiplateare 10 the articles to be vended, is prevented from m' two 2 2 uplflghtsl y the a g 60 a too fast movement after being released.

The forward end of the rod 29 is provided with a collar and a portion 36which is mounted Within a finger plunger 37 containing a spring so thatsaid plunger 37 may first be moved inward for a short distance withoutcontacting with the collar 35 by which it moves the rod 29. i

A coin controlled lock is provided for this rod, which comprises a coinrunway 38 hav ing a coin inserting slot 39; while the rear side of theplunger 37 is cutawayto receive the coin 40 which rests upon a stop 41secured to the plate 23.

Above the plunger 27 and pivoted to the plate 23 is a latch 42 having ahooked end 43 adapted to engage a notch 44 formed in the rod 29 forlocking the same against movement.

Said latch 42 is normally held in a locked position by the spring 45,and is raised to release said rod 29 by the action of the coin 40 whichengages with a pin 46 projecting from the rear side of said latch 42,the pin riding up over the coin; the cut-out portion 47 of the plunger37 pushing the coin 40 against said pin 46 as the plunger is forcedinward by the operator; while alter the coin 40 has traveled past thestop 41 it.will drop from p the plunger into a chute which will stack itin the coin box.

The stacking of the coins 40 is accomplished (see Figures 7 and 8) inthefollowing manner.

Below the plate 23 and within the casing is mounted a coin boxcomprising a box 50 having a chute 51 within which the coin drops fromthe plunger 37 and runs down an incline 52 striking a stop 53 andfalling .on its side in a pile in the holder 54; said coin box beingclosed by a door 55 having a window 56 and a lock 57 Should it bedesired to arrange the lock to be operated by a number of coins, this isaccomplished by allowing the first coins to pass through the cut-out andstack up against a stop, while the last or upper coin will register withthe cut-out portion and act as the wedge to raise the latch.

The article supports 18 may be formed with .a number of fingers 58 whichas the support descends will pass through a stripper or delivery table59 mounted in the casing.

For preventing the too rapid rotation of the sprockets 15 and a quickdescent of the suports 18 I have provided a brake or cushion device,comprising a cylinder 60 closed on its lower end and pivoted to theplate 23 so that it may swing up and down; and this cylinder 60 isprovided with a head 61 having a suitable stufiing box through which isreciprocated a stem 62 which has its outer end pivoted to the disk 24 asat 63, while'its inner end is provided with a piston 64 slidably mountedwithin the cylinder 60 and provided with a small hole 65 through which aliquid such as oil may pass; and it will thus be seen that as the disk24 rotates, all of the oil in said cylinder 60 will have to pass fromone end to the other through the small hole 65 in the piston, thusretarding the quick rotation of said disk 24 and providing a slowmovement to the conveyor 16.

I For preventing the operation of the device through the insertion ofsmall coins, slugs, etc. the plate 23 right back oi the cutout portionin the plunger is provided with an opening slightly smaller than therequired coin, so that all small coins will drop therethrough and notstay in the plunger.

Having thus described my invention, what I claim as new and desire'tosecure by Letters Patent, is-

A vending machine comprising a pair of uprights spaced apart "inparallel relation, a

lower transverse shaft journaled in said uprights near their lower ends,an upper transverse shaft adjustably mounted in said up rights neartheir upper ends, sprocket wheels mounted upon said shafts, endlessconveyors carried by said sprocket wheels, article supports pivoted tosaid conveyors and adapted to support articles upon them during theirdownward travel as actuated by the weight of the, articles, anescap-ement wheel secured on the lower shaft, an esc'apement levercoactmg therewith, a cushion device for preventingthe too rapid travelof said conveyor,

comprising a cylinder pivoted adjacent said escapement wheel, a pistonmounted therein and a'connecting rod secured to said piston and pivotedto said escapeinent wheel.

In testimony whereof I atfix my signature. GEORGE MORRISON.
